Making virt_to_pfn() a static inline taking a strongly typed (const void *) makes the contract of a passing a pointer of that type to the function explicit and exposes any misuse of the macro virt_to_pfn() acting polymorphic and accepting many types such as (void *), (unitptr_t) or (unsigned long) as arguments without warnings. For symmetry do the same with pfn_to_virt(). For compiletime resolution of __pa() we need PAGE_OFFSET which was not available to __pa() and resolved by the preprocessor wherever __pa() was used. Fix this by explicitly including <asm/mem-layout.h> where required, following the pattern of the architectures page.h file.
